Benzodiazepine poisoning in elderly.
Vojnosanitetski Pregled
|June 15, 2016
Summary
Elderly patients experiencing benzodiazepine self-poisoning face higher risks, including prolonged hospital stays and respiratory complications. Prompt medical intervention and airway management are crucial for treating acute benzodiazepine overdose in this population.
Area of Science:
- Toxicology
- Geriatric Medicine
- Emergency Medicine
Background:
- Benzodiazepines are frequently involved in self-poisoning incidents.
- Elderly individuals may exhibit increased sensitivity and impaired metabolism of benzodiazepines.
- Assessing benzodiazepine toxicity in elderly suicide attempters is critical.
Purpose of the Study:
- To evaluate the toxicity and outcomes of benzodiazepine self-poisoning in the elderly population.
- To compare the effects of benzodiazepine overdose in elderly versus younger individuals.
Main Methods:
- Retrospective analysis of 387 hospital admissions for pure benzodiazepine poisoning over 2 years.
- Patient data included demographics, ingested benzodiazepine, blood concentrations, clinical status (Glasgow Coma Score), complications, and treatment.
- Patients were categorized into young (15-40), middle-aged (41-65), and elderly (>65) groups.
Main Results:
- Elderly patients showed a significantly higher incidence of coma and longer hospital stays compared to younger groups.
- Respiratory failure and aspiration pneumonia were more frequent in the elderly.
- Flumazenil (a benzodiazepine antagonist) was more frequently administered to elderly patients.
Conclusions:
- Benzodiazepine overdose in the elderly is associated with significant morbidity, including deep coma, aspiration pneumonia, and respiratory failure.
- While flumazenil may be indicated for CNS depression, supportive care and airway management are paramount for comatose patients.
- Effective management of acute benzodiazepine poisoning in the elderly requires vigilant monitoring and prompt intervention to prevent severe complications.

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
310
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

01:15Drug Dosing: Geriatric Patients
344
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

01:19Sedatives and Hypnotics Drugs: Benzodiazepines
1.2K
Benzodiazepines have both sedative and hypnotic properties. They include compounds such as diazepam (Valium) and alprazolam (Xanax). Structurally, their cores are similar, consisting of the fusion of a benzene ring and a diazepine ring, but they share a common mechanism of action in the central nervous system (CNS).
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...

01:14CNS Depressants: Barbiturates and Benzodiazepines
1.6K
CNS depressants include drugs from the category of barbiturates and benzodiazepines. They are valuable medications for managing anxiety disorders and insomnia. Barbiturates, once used to induce and maintain sleep, have been replaced mainly by benzodiazepines due to barbiturate's toxicity, tolerance, and overdose risks. They interact with GABAA receptors, leading to sedation at low doses and potentially coma and death at higher doses. Phenobarbital, a long-acting barbiturate, possesses...

01:29Anxiolytic Drugs: Benzodiazepines and Buspirone
2.9K
Benzodiazepines are a class of anxiolytic drugs known for their rapid efficacy and high therapeutic-to-lethal dose ratio, but with a potential risk of drug dependence. These drugs are lipophilic, allowing for rapid absorption after oral administration, eventually reaching the central nervous system (CNS). Once in the CNS, benzodiazepines bind to the allosteric site of the GABAA receptor. This binding enhances the inhibitory effects of the neurotransmitter GABA. By doing so, they prevent...

01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
324
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...
